1.4. Important Safety Information
Read this before installing, operating or maintaining the inverter.
Before installation:
Check for damage to inverter and packaging. If you are in doubt, please
contact your supplier before installing the inverter. Check the voltages of
the solar modules and make sure they are within the limits of the Trannergy
inverter specifications before connecting them to the inverter.
Installation:
Only trained and authorized personnel familiar with local electrical codes
may install the inverter. For optimum safety, please follow the steps
described in this manual. Keep in mind that the inverter has two voltage
carrying sides, the PV input and the AC grid.
Disconnecting the inverter:
Always disconnect the AC line first! Afterwards disconnect the PV lines.
Note that the inverter can still be charged with very high voltages at
hazardous levels even when it is disconnected from grid/mains and solar
modules. Wait at least 5 min. before proceeding, after having disconnected
from grid and PV panels.
operating the inverter:
Before connecting the AC grid to the inverter, make sure that the
installation cover is mounted again. The inverter must not be open during
operation.
Maintenance and modification:
Only authorized personnel are allowed to repair or modify the inverter. To
ensure optimum safety for user and environment, only the original spare
parts available from your supplier should be used.
Functional safety parameters:
Unauthorized changes of functional safety parameters may cause injury or
accidents to people or inverter. Additionally it will lead to the cancelling of
all inverter operating approval certificates. The Trannergy inverters in the
TRB range are all designed according to international safety requirements.
If non-original spare parts are used, the compliance with CE guidelines in
respect of electrical safety, EMC and machine safety is not guaranteed.
1.5. General Safety Rules for Working on Electrical Equipment
All persons installing, maintaining or servicing inverters should be trained in and have
experience with the general safety rules to be observed when working on electrical
equipment.
Installation and service personnel should also be familiar with local requirements, rules
and regulations as well as safety requirements.
5
To provide a general guideline for safety precautions, five well-known and widely
accepted rules are repeated below. The list should by no means be considered as
exhaustive.
The person performing work on electrical equipment is responsible for the
safety of persons and property!
Disconnecting
Disconnect all cables supplying voltage to the working place before
starting any work. Please note that a lack of voltage is no guarantee that
disconnection has been performed.
Protecting against reconnection
Prevent the system from reconnecting by marking, closing or locking off
the work area. Unintentional reconnection may result in severe accidents.
Checking that system is voltage free
Ascertain conclusively by means of a voltage tester that the system is
voltage free. Check all terminals to ensure that the system is voltage free
(on each individual conductor).
Covering adjacent voltage-carrying components and preventing persons
from gaining access to them
Cover up all voltage-carrying system components that can harm you while
working. Make sure that danger areas are clearly marked.
1.6. System Sizing
When dimensioning a photovoltaic system, it must be ensured that the open
circuit voltage of the PV string never exceeds the maximum permissible
input voltage of 1000V DC. The PV string open circuit voltage during
parallel string operation is 910V. Higher voltages may result in permanent
damage to the inverter.
The selection of PV string output should be based on the optimum utilization of the
invested capital compared to the expected annual energy yield from the system. This
optimization depends on local weather conditions and should be considered in each
individual case.
The inverter incorporates an input power limiting device, which automatically keeps the
power at levels that are safe for the inverter. The limitation depends mainly on internal
and ambient temperatures. The limitation is calculated continuously and always allows
the maximum possible amount of energy to be produced.
Please use the tool supplied by Trannergy when dimensioning a photovoltaic system.

3. Operation mode illustration of the inverter
Vpv<150Vdc
Our inverter has five operation modes during the whole work process; they are wait,
check, normal, fault and flash modes. Its detail illustration is shown by Figure 3-1 below.
Vpv<150Vdc
Figure 3-1 State Machine of Inverter working mode
3.1. Wait mode
When the input power by solar panel is not enough to let the power module work, it is at
waiting mode. The inverter will wait until the input voltage is above 210Vdc and below
910Vdc, it turn to check mode.
3.2. Check mode
When the inverter is power on, it will check isolation, HCT device, GFCI device, relay,
fan, and soft start automatically in order. This can guarantee the inverter work normally
and turn to normal operation mode.
9
3.3. Normal mode
When the conditions above are satisfied, inverter will let the BOOST and inverter module
work and turn to normal generating power mode. It will change the solar energy into
electrical energy and fed it into grid based on advanced MPPT technology in order to
absorb solar energy in maximum extent possible. It will also calculate the generated
energy per day/per month/per year automatically, save the number in EEPROM and the
number can be read from the HMI.
3.4. Fault mode
When there are fault during the inverter running, it will stop generating power and turn to
fault mode and display the fault information on LCD. Before do this, it will store the
generated power number into EEPROM automatically. Many not very serious fault will
be cleared after 5s automatically and retry to run. If the serious fault generated, it will
stay in the fault mode until the technical staff to solve the problem.
3.5. Flash mode
Regardless the inverter running in which mode above, when there is the flash command,
it will turn into flash mode and rewrite the firmware in DSP flash.
3.6. Shut down
When the PV input voltage less than 150Vdc, the PV panel can’t provide energy enough,
so the inverter shut down automatically. When next day come, with the irradiance
increasing, it will run again smoothly if there are no fault occurrence.

One inverter can only be communicated with one PC at the same time through RS-232
port. Thus this method is generally used for three inverter’s communication, for examples,
software updating and serviceman’s testing.
6.2.2. RS-485/422 Communication
RS-485/422 is generally for multi inverters’ communication. It can communicate with
and up to 32 inverters could communicate at the same time, but wire length should be ≤
1200 m. Connect the system as blow (Figure 6-2), user can easily monitoring the PV

7. Maintenance and Repair
7.1 Routine maintenance
Generally, the inverter needn’t to maintain or calibrate, but you need to ensure the heat
sink uncovered by the dust or dirty things.
In order to prove the inverter’s normal function and long life, you best to clean the
inverter and heat sink regularly and ensure there is enough space for air flow around the
heat sink. You can use the compressed air, soft cloth or brush to clean the surface of
inverter and heat sink. Please don’t use water, corrosive chemicals or strong detergent to
clean them.
7.2 Notes of maintain or service
When there are faults occurrences, the inverter can disconnect from grid automatically
and send out fault or warning information. The simple fault approaches refer to appendix
A (FAQ) please.
7.3 Safety for maintain or service
Before you handle the fault, you must open the DC and AC circuit
breaker first and prove others can’t close it again without your
permission.
The inverter must only be opened by qualified personnel for repair.
The inverter can still be charged with hazardous voltages even when
it is disconnected from the PV modules and the grid. Measure the DC
bus voltage, which must be lower than 48V, before starting work on
the electronic system inside the cabinet.

SCI Failure
Check whether the inverter is earthed and test impedance
between PV (+) & (-) and the impedance must exceed
3MΩ;
2. Check whether the AC-side has contacts with earth.
2.
Wait for 5 minutes, if the grid returns to normal, PV
inverter automatically restarts.
Make sure grid voltage and frequency meet the local
specifications.
AC HCT Fault
GFCI Failure
39
If the PV DC voltage is higher than 200V, while the inverter still doesn’t work, please call the
local service.
During periods of little or no sunlight, the inverter may continuously start up and shut down.
This is due to insufficient power generated and it is normal working state. If sunlight
strengthens or energy increase to support the inverter’s startup, while the problems remain,
please call service.
Except the frequent problems as above, if you still have any problems which cannot be solved,
please contact us and we will offer the best services as we can.
